2.3 COOLING AND VENTILATING AIR

•Line the compartment interior walls and floor, as well as the underside of the floor, with 26-gauge galvanized steel.

•Vapor seal all compartment seams and joints.

•Over the galvanized steel lining, install a combi- nation of acoustical materials as mentioned in "Sound Insulating Materials".

DANGER

To prevent fire or explosion, do not install any insulation or other absorbent materials on the interior or underside of the compartment floor.

•Seal all compartment door edges to prevent noise leakage around the door perimeter.

•Line the compartment door interior (except for air openings) with suitable, fireproof sound insulation (such as 1-inch (25 mm) thick fiberglass with a 2- pound density).

‹2.2.5 COMPARTMENT FLOOR CUTOUTS

Provide openings in the generator compartment for the following items (Figure 2.8 on page 26):

•Engine exhaust and cooling air outlets

•Generator cooling air inlet

•Four holes for passage of generator mounting bolts (see "Generator Restraint").

DANGER

Fuel lines and exhaust piping must not pen- etrate into the vehicle living area.

It is absolutely essential that an adequate flow of air for cooling, ventilating and engine combustion be supplied to the generator set. Without sufficient airflow, the engine/generator quickly overheats. Such overheating can cause serious operating difficulties and also may cause fire and personal injury. The installer must make sure that sufficient air is avail- able to the generator for cooling, ventilating and combustion. The installer also must provide for a path for exhausting the cooling air to the exterior of a compartment, if so equipped.

DANGER

Never use discharged cooling air for heating or permit such air to enter the vehicle interior. This air contains deadly carbon monoxide gas and other poisonous, flammable or explosive gases.

‹2.3.1 GENERATOR AIRFLOW

Engine operation drives cooling fans for the two-stage cooling air system. A pressure fan draws cooling air into the bottom right side of the generator (Figure 2.9). This airflow cools the engine/generator and electronic components. The second part of the cooling system, a suction fan, draws air that is heated from a hot engine into a collector compartment at the left side of the unit. This heated air (although cooler than exhaust muffler) is then deflected out the bottom toward the ground.
